openMVG安装 /anaconda3/lib/libpng16.so.16: undefined reference to `inflateValidate@ZLIB_1.2.9‘

问题描述

在安装openMVG make的时候出现报错如下：

[ 82%] Linking CXX executable ../../Linux-x86_64-RELEASE/openMVG_sample_describe_and_match_GUI
/home/XXX/anaconda3/lib/libpng16.so.16：对‘inflateValidate@ZLIB_1.2.9’未定义的引用

解决方案

网上有很多相关解决方案，比如修改~/.bashrc中的anaconda3相关环境变量，然而并没有用，最后是这么解决的：

首先参考博客：openMVG安装&&问题解决
将/anaconda3/lib/路径下的libpng16.so.16手动删除，然后make发现出现了更多的报错。

接着参考博客：Linux(CentOS, ubuntu)报错：libpng16.so.16: 无法打开共享对象文件: 没有那个文件或目录
使用apt-get命令安装libpng:

sudo apt-get install libpng16-16

没有报错，成功编译！
